(Cl. 12S- 146) 3 Claims. l

This invention relates to nasal and lung protectors, and aims to providean efficient and practical protective means for use by workers in suchtrades or industries where fine particles of dust or liquid globules arepresent in the ambient at.- mosphere, whereby the worker can breathefreely without inhaling the dust or liquid particles. It is well knownthat serious trouble can result from such inhalation, and it is believedthat the utilization of the protector herein presented will effectivelyprevent such particles from being breathed in by the worker.

The above broad as well as additional and more detailed objects willbecome apparent in the following description, wherein characters ofreference refer to like-numbered parts in the accompanying drawings. Itis to be noted that the drawings are intended for the purpose ofillustration only, and that it is neither desired nor intended to limitthe invention necessarily to the specific details of construction shownexcepting insofar as they may be deemed essential to the invention.

Referring briefly to the dawings,

Fig. l is a front elevational View of the pro tective hood.

Fig. 2 is a rear elevational view of the same.

Fig. 3 is a cross-sectional View taken on the line 3-3 of Fig. 1.

Fig. 4 is a cross-sectional view taken on the line 4--11 of Fig. 1.

Fig. 5 is a cross-sectional view taken on the line 5 5 of Fig. 1.

Fig. 6 is a fragmentary side elevational view of the protector.

Referring in detail to the drawings, the numeral Ill indicates theshoulder portion and the numeral II the head portion of a cape-like hoodadapted to cover the head, neck and shoulders of the wearer. The headportion II comprises a substantially cylindrical member having the frontand rear walls I2 and I3, respectively, joined by the enclosingperipheral side wall Ill having an opening I5 at the bottom for the neckof the wearer. The shoulder portion Ill, which is shaped as seen inFigs. 1 and 2 to register over the shoulders and part of the necl of thewearer, comprises at the rear the cover or back I3 which is a unitarycontinuation of the head portion I3. At the front of the shoulderportion Ill, the cover member I1 depends from the lower portion of thehead portion I0. Shoulder strips i8 join the complementary upper edgesof the shoulder cover members I6 and I1.

An opening I9 is formed in the member I2 to provide a vent for themouth, and around this opening a fiange 23 is formed about which a cap2| is slidably mounted, the outer end of the .cap having the opening 22therethrough surrounded by the flange 23. A perforated closure strip 24,backed by a lter pad of any desired construction or material 25, whichregisters against a ller flange 26 mounted within the ange 20, serves topermit air to enter through the opening I9, and the lter serves to trapany dust or liquid particles which may abound in the air. The cap 2| isreadily removable from the flange 26, being retained thereonfrictionally, for replacement .of the filter and cleaning the perforatedclosure 24.

Spaced eye openings 21 are likewise formed in the face member I2, and acircular flange 28 surrounds the same, about which registersfrictionally the cap having its end 36 open and provided with the flange3|. An inner filler flange 32 is mounted within the flange 28, and aplain glass disk 33 is thus removably clamped between the flanges 3| and32, so that the glass may be removed for cleaning. The eye openings arethus sealed.

A nose opening 3d is also formed in the face member I2, surrounded bythe flange 35, in which a filler flange 36 is mounted. A cap 3'1frictionally and removably surrounds the flange 35, and its end is openat 38 and surrounded by the flange 39. Behind the ange 39 a perforateddisc 40, backed by a filter pad lil, registers, and both the disc andthe pad are thus removably clamped between the flanges 39 and 36, sothat both may be removed readily for cleaning or replacement. Theconstruction of the ear members 42 is substantially similar to thatshown for the nose member, and the ear members have therefore not beenillustrated in detail.

The bottom of the shoulder member Il] is, of course, although not shown,open, so that the entire hood may be slipped on the wearer over theshoulders, with the head registering in the portion I0. Of course nodimensions are shown or indicated, but it is to be understood that thevarious parts of the device are to be so proportioned and dimensioned asto permit its functioning as and for the purposes set forth.

When the hood is used in the manner stated, the wearer may breathefreely through the nose member or, also, the mouth member, and he mayheal` through the ear members and see through the eye members. Meanwhilethe hood fits the entire shoulder, neck and head of the wearer, coveringthose parts completely so that no dust or liquid particles may bebreathed in while he contaminated. In this Way the worker is protectedfrom the consequences, which are frequently serious, of inhaling suchparticles into his nasal or sinus passages and the lungs.

The entire device may be readily and inexpensively made of any suitablematerial, such as, 'for instance, a cellulose acetate plastic material,or any other plastic material which may be adaptable to the purpose. Thematerial would be light in'weight yet sulciently sturdy. To facilitateputting the hood on or taking it off, a slide fastener closure IEB isprovided at the vertical median line of the back member I3-I6, extendingfrom a point near the top of the head member to and through the loweredge of the back shoulder member I6. The wearer himself may, therefore,readily apply or remove the hood on himself. When the hood is thus worn,and the slide fastener closed, the lower peripheral edge of the shouldermember I closes snugly about the shoulders of the wearer and therebyprevents leakage of dust-laden air into the hood.

The feature of making the mouth, nose, eye and ear closures removablefor cleaning or replacement of the filters,` is important in that suchcleaning or replacement may be made quickly and readily With a minimumloss of time to the Worker.

Obviously, modifications in form and structure may be made withoutdeparting from the spirit and scope of the invention.

I claim:

1, A hood of the class described comprising a unitary head member andshoulder member, said head member comprising a substantially cylindricalhollow member having front and rear faces having openings through theface thereof for eyes, nose, and mouth, and openings through the frontcylindrical wall thereof for ears, said nose, mouth, and ear openingshaving perforated closures removably mounted therein and havingremovable lters mounted therein behind said closures, said hood havingslide fastener means for tightening the lower edge of the same about theshoulders of the wearer.

2. The hood set forth in claim 1, said slide fastener means beingpositioned along the vertical median line of the hood at the backthereof and extending from a point near the top of said head member downto and through the lower peripheral edge of said shoulder member.

3. The hood set forth in claim 1, said eye members having glass disksremovably mounted therein.
